Setting objectives and providing feedback
Questions, cues, and advance organizers
Summarizing and Notetaking
Nonlinguistic interpretations
Lesson on:
DNA
Grade 8 Bridge
Curriculum Area
Science
Grouping
Whole/Groups
Content Obj.
To describe the structure of the double helix DNA and explain its function
Language Obj.
Students will be able to express verbally their understanding about the structure of the DNA
CMT Strand:
C 1.Describe how genetic information is organized in genes on chromosomes,
and explain sex determination in humans.
Materials:
LCD Projector and interactive websites.
Vocabulary:
DNA Adenine
Genes Cytosine
Chromosomes Guanine
Mitochondria Thymine
Grammar:
Students will write the vocabulary words and the meaning in their Interactive Science Notebook in which they use Cornell Notes to take accurate notes on the lesson.
I will state to my students what the objectives for today are, they will have to write them on their interactive science notebook in a Cornell note style.
I will start my class by asking students to tell me what they know about DNA? And where they heard it from?
Links of concepts to students' experience
Have you seen forensic evidence or any movies
that mentions DNA? Why you think DNA is so important?
Procedure I will use an LCD Projector in order to use the DNA Interactive Timeline website. Students will have time to take accurate notes of the lessons. Next students are going to play a puzzle game using the chemical bases Adenine, Cytosine, Guanine and Thymine. For this section we are going to use the second website and we are going to enter the section Build a DNA Chain. Students are going to have an opportunity to come to the computer and add a section of the chain. Closure Quickly we will review what they learned during the lesson about DNA. I will refer back to the objectives provided at the beginning of the lesson. I will let them know what we will be learning next. For that we will use the third interactive website in which students will have the opportunity to extract DNA in an interactive laboratory in which they will be doing the extraction. I will reserve the computer lab for the next lesson so that each student can enjoy the interactive laboratory to the full capacity. Assessment I will assess students by using the Red Robin strategy, using a plush toy tossing it around while asking students to tell me what they learned today.
